I'm having trouble finding 42# or 42.5 injectors for the 95 Camaro 3.4. Anyone I speak to only confirms the stock fuel injector. A part number or compatible part would be much appreciated.

Are you sure you have that number right?

If your referring to the size, yes. It's a turbo application and I was told this should be a perfect fit. Do you disagree? I'm open to suggestions.

I don't know what you are doing, so no, I don't have any suggestions. Here is an old thread discussing turbo injectors that may be of some help.

I will do some homework, thanks.

How much boost are you running?

10 pounds of boost, it looks like I'm going with 28lb injectors.

I think the LS1 F-bodies came with those stock if they are the correct style...

I am currently using the Ford 19 lb injectors on a turbo 3.4 push rod engine with about 7-8 psi of boost. It was very rich until some custom tuning work was performed. Are you certain that you really need the 28 lb injectors? If so I would appreciate your sharing this specific size requirement so that I can consider upgrading mine.

If your injectors are Ford, then they are more like 22# injectors since they are rated at 19# @ 12v and the Fiero runs closer to 14v.
More voltage = more flow.

I ended up with Ford Cobra 24lb injectors, I'll post results after installation.

Cool. Those should run like GM 28#'ers...

Wrong. With the exception of a SLIGHTLY slower opening time, voltage will not change injector flow. Ford injectors are typically rated at 43.5psi and most GM injectors seem to be talkd about in a 50psi scale.

Funnily enough the math works out the same...so who cares who is actually right.
